Fedora Server 34 Crashes on HP ProLiant DL380e G8 – Troubleshooting Guide

I am unfortunately having a problem with my HP ProLiant DL380e G8 server running Fedora Server 34. I suspect these are memory errors or a DIMM being/going bad, however I'm not sure.

Feedback is very welcome!

I've ran journalctl -r, which returns the following output in the PasteBin link (a snippet of what looks out of the ordinary): https://pastebin.com/KPUZHceD

All help and ideas are appreciated!

Kind regards
